CHARLES MUELLER, OF LAFE, ARKANSAS.

COLTER-FASTENER.

SPECIFICATION forming part of Letters Patent No. 762,079, dated June 7, 1904.

Application filed September 5, 1903. Serial No- 172,128. (No model.)

To all whom it may concern:

Be it known that I, CHARLns MUELLER, a citizen of the United States, residing at Lafe, in the county of Greene and State of Arkansas, have invented a new and useful Colter-Fastener,of which the following is a specification.

This invention is an improved construction of colter-fastener, the object being to provide an exceedingly simple and durable device by means of which the shank of the colter can be securely locked to the plow-beam.

Another object is to provide a device of such construction that the said shank can be quickly and easily disconnected from the plow-beam when so desired; and with these objects in view the invention consists, essentially, of a plate having an opening through which the shank of the plow-colter is adapted to pass, said plate having parallel apertured ears in which is arranged a bolt having areduced central portion which is adapted to be brought into alinement with the opening in the plate, said bolt having a lever connected to one end thereof and by means of which the said bolt is turned in the apertured ears,-so as to bind the unreduced portion of the bolt against the shank of the colter.

The invention consists also in certain details of construction hereinafterfully described,and pointed out in the claim.

In the drawings forming part of this specification, Figure 1 is a view showing the practical application of my invention. Fig. 2 is a top plan view of the same, the shank of the colter being shown in section. Fig. 3 is a vertical sectional view, the shank of the colter being shown in elevation. Fig. 4 is a detail perspective view of the locking-bolt and operating-lever.

Referring to the drawings, A indicates an ordinary woodenplow-beam having an opening A produced therein and through which the shank B of the colter is adapted to be passed, and inasmuch as the colters are ordinarily arranged at an oblique angle the opening A is preferably made upon an angle. A

"plate Ehaving an opening E, which also corresponds and alines with the opening A.

The plate C is formed with a pair of parallel ears F, having circular openings F, and mounted in these ears is a locking-bolt Gr, having a lever H connected to one end thereof, said lever having a lateral extension H, which is adapted to'engage the top of the plow-beam and limit the downward movement of the lever. The bolt G is reduced or cut away intermediate its end, said reduced or cut-away portion being in alinement with the opening C in the plate 0. In operation when the shank of the colter is passed through the plowbeam and through the opening C in the plate 0 the bolt Gr is turned so that the reduced portion G will coincide with the rear end of the opening C. The lever H is then thrown down, turning the bolt G in the ears F and bringing the unreduced portion of the bolt into engagement with the rear edge of the colter-shank, thereby acting as an eccentric and tightly binding the said shank in the plowbeam. It will thus be seen that the said colter can be quickly and easily locked in the plow-beam, and when it is desired to disconnect the colter it is only necessary to raise the lever so as to bring the reduced portion of the bolt into coincidence with the rear end of the opening C, and all strain or pressure is then relieved from the shank, and it can be quickly and easily removed from the plow-beam.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

A colter-fastener comprising the upper and lower plates having openings therein, the upper plate having apertured ears upon opposite sides of the opening and adjacent one end of ver having a projection, substantially as set said opening, the bolt circular in cross-section forth.

. to one end of the bolt, the free end of said le- GHARLES MUELLER.
